DEVICE FOR HANGING TRANSOMS.'

SPECIFICATION forming part of Letters Patent No. 268,367, dated November 28, 1882.

Application filed June 12, 1882. (No model.)

To all whom it may concern Be it known that I, JOHN KIRBY, JR., of Ludlow, Kenton county, Kentucky, have invented a certain new and useful Improvement in Sash-Pivots; and Ido declare the following to be a full, clear, and exact description ofthe same, reference being had to the accompanyingd ra wings, forming partofthis specification, in which- Figure l is a perspective view with the sash in position to be removed, Fig. 2 is a perspective view with the sash removed. Fig. 3 is a perspective view of my bolt-and ratchet plate with its bolt-hole and depressions. Fig. 4 is a perspective view of my pivot-bolt and ratchet-bolt holder or casing.

Similar letters of reference refer to the same parts in the several drawings.

M y invention relates to pivots for sash, more especiallytothatknown asdeck-sashforrailway-ca rs and it consists First, in placing two spring-bolts, E and D,

in one casing, M, said casing being provided This plate has in it bolt-hole A, groove My invention is used as follows, viz: The beltand-ratchet plate N is firmly screwed to the upright of the casing K, being flush with the surface thereof. The sash L is then passed through the casing at an angle and brought down square with the casing. The bolts E are then pressed back until they will pass into groove B, and then, the pressure being taken off the thumb-pieces, into bolt-hole A. \Vhen the sash and pivot-bolt are in this position bolt D is resting in groove B. Now, it the sash be raised, bolt D will slide into any of the recesses or depressions O O O by reason of its wedgeshaped or tapered end, so that the sash may be held in four positions without the aid oi other mechanism. The sash may be removed by bringing'it to its first position and retracting the pivot-bolts.

Having thus described myinvention, what I claim as new, and desire to secure by Letters Patent, is as follows:

The sash-pivoting device consisting of the ratchet-plate N, having bolt-hole A, groove B, and depressions (J, and of the bolt-casing M, containing spring-bolt E, furnished with a thumb-piece, F, and spring-bolt D, having a beveled nose, substantially as described.

The foregoing specification of my invention signed by me this 5th day of June, A. D. 1882.
